Whether we like it or not, it appears that John Mozeliak and the Cardinals think that Paul Goldschmidt is a worthy alternative to Bryce Harper. Derrick Goold has indicated as such - that the Cardinals aren’t going after Harper because they already got Goldschmidt. Let’s ignore that that makes no sense, but that at least appears to be the excuse they’re going with for some reason.
Ignoring the fact that there is no reason Goldschmidt and Harper can’t both be gotten, it stands to reason that if you think Goldschmidt is a worthy alternative to Harper, they plan to have him for more than one year.
